Fundamental Studies and the Optical Diagnostics of Laboratory Plasmas (Physics)

该计划的主要目的是研究湍流等离子体中的离子扩散和输运，这是一个广泛应用的主题，例如对边缘托克马克物理和磁层等离子体。这些实验广泛使用激光诱导荧光(LIF)和光学层析成像技术，利用加州大学欧文分校、欧文：Q-Machine、欧文环面和欧文磁镜的独特等离子体配置。使用这些诊断技术，研究人员能够在具有起伏磁场的等离子体中建立测试粒子，跟踪它，并将实验测量结果与理论预测进行比较。重点将放在与扩散理论的比较上。此外，他们还将利用激光诱导荧光技术研究等离子体中随机性的转变。其他项目包括模式耦合、波发射、尘埃等离子体和诊断开发的研究。

A major thrust of this program is the study of ion diffusion and transport in turbulent plasmas, a topic of wide application, for example to edge-tokomak physics and to magnetospheric plasmas. The experiments make extensive use of laser induced fluorescence (LIF) and optical tomography techniques taking advantage of the availability of unique plasma configuration at U. Cal., Irvine: the Q-Machine, the Irvine Torus, and the Irvine Magnetic Mirror. Using these diagnostic techniques the investigators are able to establish a test particle in a plasma with fluctuating fields, follow it and compare experimental measurements with theoretical predictions. The focus will be on comparison with diffusion theory. In addition, with LIF techniques they will investigate the transition of stochasticity in plasmas. Additional projects include studies of mode coupling, wave launching, dusty plasmas, and diagnostic development.
